Currently, x i. y signals length error when the
rank r cells of y do not have the same shape as the
the rank r cells of x, where r=:0>.(#$x)-1 is the
rank of an item of x . For example:
x=: i.10 2 3
y=: i.4 5 2 4
x i. y
|length error
| x i.y
I propose to change this to return #x for each
rank r cell. Thus:
x i. y
10 10 10 10 10
10 10 10 10 10
10 10 10 10 10
10 10 10 10 10
One jusification for this change is that x i. y
already returns #x for cells having a wrong type,
a situation no less egregious than having a wrong
shape.
x i. 4 2 3$'deipnosophist'
10 10 10 10
i: e. -. will also be changed correspondingly.
